Learn the concept of electrostatics, DC circuits, magnetic field, electromagnetic induction in College Physics 2, practice how to do calculation of charges and forces, current and resistance and magnetic field.
Electrostatics deals with attractions or repulsions of electric charges but it does not dependent on their motion. In this chapter we will learn to practice on electric charges and forces, electric field and field lines, and electric potential i.e., coulomb’s law, charges under equilibrium, electric field due to point and continuous charge distribution, electric field lines, potential due to continuous charge distribution and calculation of potential from electric field. We will also practice on flux and Gauss’s law i.e., Gauss law and calculation of electric flux and calculation of electric field using Gauss’s law.
A circuit in which the current flows in only one direction is called DC (Direct Current) circuit. In this chapter, we will practice on current and resistance, circuit analysis and capacitance i.e., resistance variation due to temperature, EMF and potential, Kirchhoff’s rules, electric appliances, calculation of capacitance and equivalent capacitance. We will also practice on advanced problems involving capacitors i.e., application of kirchhoff’s rule involving capacitors, energy stored in a capacitor, RC circuit, and dielectric.
When a charge moves in the presence of magnetic field, then the magnetic field exerts a force on it, which is known as magnetic force. In this chapter, we will practice on calculation of magnetic field and force on moving charge i.e., direction of magnetic field, Biot Savart’s law and Ampere’s law. We will practice on effects of magnetic field on current carrying wires and loops i.e., force on current carrying wires, parallel current carrying long wire and magnetic moment and torque.
Electromagnetic induction is the process of producing induced emf in a conductor by changing the electric or magnetic field. In this chapter, we will learn to practice on basic concepts of flux and EMF, motional EMF and induced electric field i.e., change in magnetic flux, average and instantaneous value of induced EMF, Lenz’s law, basic and advanced problems of motional EMF and induced electric field. We will also practice on inductance and AC circuit i.e., self inductance, RL circuit, mutual inductance, LC oscillations, average and RMS values, AC with resistance, inductance and capacitor and LCR in series.
